SOLE-EDGE TRIMMER.

SPECIFICATION forming part of Letters Patent No. 674,119, dated May 14, 1901.

Application filed September 4, 1900. Serial No. 28,879- (No model.)

This invention relates to machines or tools for trimming the edges of the soles of boots and shoes, and particularly to tools of the type shown in Letters Patent of the United States No. 625,115, in which a tool is shown com prising a series of on ttersand edge-guards occupying spaces between the cutters and arranged so that channels are left between the cutters and the guards for the escape of fine cuttings and dust inward toward the center of the trimmer, said guards limiting the depth of cut of the cutters into the edge of the sole.

The present invention has for its object to enable the guards to be rigidly secured in,

place and easily and conveniently applied and removed.

The invention consists in the improvements which we will now proceed to describe and claim.

. Of the accompanying drawings, forming a part of this specification, Figure 1 represents an end elevation of the cutter member. Fig. 2 represents a side elevation of the same. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4 represents an elevation of the outer end of the guard cup ormember. Fig. 5 represents a side elevation of the same. Fig. 6

represents an elevation of the inner end. of.

the guard-c up. Fig. 7 represents a section on line 7 7 of Fig. 4. Fig. 8 represents-a side elevation of the cutter and guard-cup connected. Fig. 9 represents a section 'on line 9 9 of Fig. 8. Fig. ldrepresent-s a section on line 10 10, Fig. 9.

The same reference letters and numerals indicate the same parts in all the figures.

In the drawings, a represents the cutter member, which is spider-shaped, and comprises a hub 2, formed to fit upon the driving-spindle b, arms 3, radiating tangentially from the hub, and-cutters 4., formed on the outer portions of tlitjl'ms and having their front ends 5 ground at an acute angle, with vided with a circular boss or offset 9, formed to enter the cavity of the hub, as shown in Fig. 10. margin of the end plate 8 and are formed to enter the space between the cutters 4, the

margin of the end plate being cutaway or re-. duced between the guards to form recesses 12, Figs. 6 and 9, which receive the cutters -t, A

cutting edges 7, so that the said outer faces The guards 10 10 extend from the limit the thickness of the cuttings removed 1 from a sole edge by thecutters. The width of each guard is less than the width of thespace between two adjacent cutters, so that there'is a sufficient opening between the cutting edge of each cutter and the adjacent guard for the passage of fine cuttings and dust into the interior of the cutter. The outer ends of the guards are connected by short arms or necks 14, Figs. 7 and 10, with an externally-threaded ring 15, whichprojects from the outer end of the series of guards and supports the annular upperguard or shield (Z, said shield being'internally screw-threaded to engage the thread of the ring 15 and provided with orifices 16 to engage a spanner by which it. may be turned to screw it onto the ring 15.

It will be seen that the guard member has the general shape of a cup, of which theplate 8 forms the bottom, the guards 10 the margin, and the ring 15 and shield (Z the mouth. The ring 15 being integral with the guards and forming a connection between their outer' ends imparts,with the shield, a-mplestiffness and rigidity to the guards, each guard being rigidly supported atits inner end by the plate 8 and at its outer end by the ring 15 and shield (Z.

The guard-cup is attached to the cutter and 100 shaft by the screw e, which also attaches the cutter-to the shaft, as shown in Fig. 10.
